Attachments missing in Outlook 2010 but show in Web APp

    Question

  • There was another thread showing this but the answer provided does not seem to apply.  Exchange 2010 SP1 running as virtual system on Server 2008 R2.  4 cores, 12 GB of RAM, 60 GB of free disk space. 

    Had an e-mail come in addressed to 2 different people and neither showed the attachment.  Forwarded e-mail to my account.  Using Outlook 2010 on all systems.  The forwarded mail shows as an attachment of 3MB but when I open it, it is just the message with no attachments.  Open my Outlook Web App and the same e-mail now shows the attachments.   I believe the fact that 3 different accounts show the same result eliminates the possibility of corrupt Outlook profiles. 

    Have rebooted the Exchange server with no change.

    Any help would be appreciated!

    Thanks,
    Eric

  • Is there any firewall hardware on your local network?
    What is kind of your attachment?  
    Can you receive the same attachment which is compress by zip or winrar ?
    Special format attachment will be blocked by outlook or firewall.
    It is the way to receive special file by outlook.

    1.     Make sure Outlook is closed.

    2.     Open your registry editor by opening the Run command and type regedit (regedt32 for Windows 2000).
    In Windows Vista and Windows 7 you can also directly type regedit in the Start Menu’s Search box.

    3.     Locate the following key

    §  Outlook 2000
    [HKEY_CURRENT_USER\Software\Microsoft\Office\9.0\Outlook\Security]

    §  Outlook 2002
    [HKEY_CURRENT_USER\Software\Microsoft\Office\10.0\Outlook\Security]

    §  Outlook 2003
    [HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\Outlook\Security]

    §  Outlook 2007
    [HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Outlook\Security]

    §  Outlook 2010
    [HKEY_CURRENT_USER\Software\Microsoft\Office\14.0\Outlook\Security]

    4.     Go to Edit-> New-> String Value and name the value Level1Remove (case sensitive!)

    5.     Double-click on the newly created value and enter the extension including the "dot" that you want to open in Outlook. For instance .exe
    If you need to enter more than one extension you'll have to type separate them by a semicolon like this;
    .exe;.bat;.url

    6.     Press OK on the input box and close the registry editor

    7.     When you open now Outlook, the attachments which hold those extensions aren't blocked by Outlook anymore.

    To let Outlook block those extensions again follow the instructions again but instead of creating the Level1Remove value delete it.

    Another way is to move this mailbox to another database. Maybe there is little corruption in this database.

  • Hi,

     

    I'm having the same issue with Exchange 2007 and Outlook 2010 after applying SP3 to exchange. Attachment is definitely allowed as this was PDF. So far it was seen by 3 of my users. when you see an email in the inbox, the icon shows the message is with attachment, but when you open the message or forward it, no attachments are present. Still if you go to OWA and forward this email then, attachments are included in the message.

     

    Thanks, Marcin

  • Same issue Exchange 2007, Outlook 2010.  PDF's are allowed.  Sometimes PDF come through sometimes they don't.  OWA works if you logon and forward, still can't open atttachment via OWA unless you forward.

  • I'm having the same exact issue as JoeCA12.  I have a user that sometimes gets a PDF attachement and sometimes doesn't.  If she forwards the message to GMAIL she is able to download the attachment and even resend it to someone.  The attachment shows in OWA but not able to download.  I am able to see it also through Active Scyn on Android phone. 

    I tried the registry suggestions but no luck.  Any other suggestions?

  • I have seen this exact same problem with my work PC running Office 2010, previously had 2007 and had the same issue with a server running exchange, and also my home PC which is stand-alone running Office 2007.

    The type of attached file is irrelevant. It can be a pps or pdf or a picture, whatever. Sometimes I will get an email and I can see from teh size that there should be an attachment but there is nothing shown. Forward it to anyone else and they see the attachment.

    It can't be setting because it should then happen with ALL attachments on that type which is not the case. I will receive 2 emails on the same day both with pdf attachments. One I can see, one I can't. I have even had a case where I forwarded the email to my Gmail account and then forwarded it back to my Outlook account and then I could see it! This is a bug in Outlook.

  • I think I may have figured out how to find the attachment.  I have my inbox set in conversation view.  If you check the email with the supposed attachment it shows the paperclip but no file is attached.  Even if you go to download attachments there are none.  When I check the sent folder it does not show an attachment either.  

    Now if you go to the message that supposed to have the attachment then forward it to another email that recipient WILL NOT get the attachment either BUT when you check your sent history all of a sudden that file is attached to the email that you ORIGINALLY were trying to find that attachment in (but in the sent section)

  • Do you know if this will be fixed in Outlook 2010?  I often use Yahoo's web mail server to read and write e-mail, move sent e-mail from my Yahoo sent box to Yahoo inbox, and later download it all into Outlook 2010.  When I send a PDF attachment to someone and later download my own e-mail, Outlook 2010 shows the clippy icon saying that there's an attachment, but Outlook 2010 doesn't display the attachment itself.  Outlook 2010 sometimes works and sometimes doesn't work.  I doubt very much that the server side matters at all (Exchange or Yahoo or anyone else).  I looked at Yahoo web mail again and the attachment is really there.
